Search for Lepton-Flavor-Violating $τ$ Decays to a Lepton and an Invisible Boson at Belle II

Belle II Collaboration, I. Adachi, K. Adamczyk +398

We search for lepton-flavor-violating $τ^{-} \to e^{-} α$ and $τ^{-} \to μ^{-} α$ decays, where $α$ is an invisible spin-0 boson. The search uses electron-positron collisions at $10.58$ GeV cen…

Study of $e^{+} e^{-} \to Σ^{0} Σ^{0}$ and $Σ^{+} Σ^{-}$ by Initial State Radiation Method at Belle

Belle Collaboration, G. Gong, L. K. Li +195

The processes $e^{+} e^{-} \to Σ^{0} Σ^{0}$ and $e^{+} e^{-} \to Σ^{+} Σ^{-}$ are studied using initial-state-radiation events in a sample of 980 $\,\mbox{fb}^{-1…

Measurement of the branching fractions and $C P$ asymmetries of $B^{+} \to π^{+} π^{0}$ and $B^{+} \to K^{+} π^{0}$ decays in 2019-2021 Belle II data

Belle II Collaboration, F. Abudinén, I. Adachi +582

We determine the branching fractions $B$ and $C P$ asymmetries $A_{CP}$ of the decays $B^{+} \to π^{+} π^{0}$ and $B^{+} \to K^{+} π^{0}$ . The result…

Measurement of the branching fraction and search for $C P$ violation in $D^{0} \to K_{S}^{0} K_{S}^{0} π^{+} π^{-}$ decays at Belle

Aman Sangal

We measure the branching fraction for the Singly Cabibbo-suppressed decay $D^{0} \to K_{S}^{0} K_{S}^{0} π^{+} π^{-}$ , and we search for $C P$ violation via a measurement of the $C P$ asym…

Search for $C P$ violation and measurement of branching fractions and decay asymmetry parameters for $Λ_{c}^{+} \to Λ h^{+}$ and $Λ_{c}^{+} \to Σ^{0} h^{+}$ ( $h = K, π$ )

Belle Collaboration, L. K. Li, W. Shan +187

We report a study of $Λ_{c}^{+} \to Λ h^{+}$ and $Λ_{c}^{+} \to Σ^{0} h^{+}$ ( $h = K, π$ ) decays based on a data sample of 980~ $fb^{- 1}$ collected with the Belle detector at the KEKB energ…
